一、Spring Data Redis

​1、Spring-data-redis简介

​Spring-data-redis提供了在Spring应用中通过简单的配置访问redis服务,对reids底层开发包(Jedis, JRedis, and RJC)进行了高度封装,封装了 RedisTemplate 对象来进行对Redis的各种操作、异常处理及序列化,支持发布订阅,并对Spring 3.1 cache进行了实现,它支持所有的Redis原生的 API。

2、Spring-data-redis 针对 Jedis 提供的功能

1、连接池自动管理,提供了一个高度封装的“RedisTemplate”类;
2、针对jedis客户端中大量api进行了归类封装,将同一类型操作封装为operation接口

ValueOperations:简单的K-V操作SetOperations:set类型数据操作ZSetOperations:zset类型数据操作HashOperations:针对map类型的数据操作ListOperations:针对list类型的数据操作

3、提供了对key的“bound”(绑定)便捷化操作API,可以通过bound封装指定的key,然后进行一系列的操作而无须“显式”的再次指定Key,即BoundKeyOperations:

BoundValueOperationsBoundSetOperationsBoundListOperationsBoundSetOperationsBoundHashOperations

4、将事务操作封装,有容器控制。
5、针对数据的“序列化/反序列化”,提供了多种可选择策略(RedisSerializer)

JdkSerializationRedisSerializer:POJO对象的存取场景,使用JDK本身序列化机制,将pojo类通过ObjectInputStream/ObjectOutputStream进行序列化操作,最终redis-server中将存储字节序列。是目前最常用的序列化策略。StringRedisSerializer:Key或者value为字符串的场景,根据指定的charset对数据的字节序列编码成string,是“new String(bytes, charset)”和“string.getBytes(charset)”的直接封装。是最轻量级和高效的策略。JacksonJsonRedisSerializer:jackson-json工具提供了javabean与json之间的转换能力,可以将pojo实例序列化成json格式存储在redis中,也可以将json格式的数据转换成pojo实例。

在项目中,我们经常会用到RedisTemplate来操作Redis,本文详细罗列了RedisTemplate操作Redis的方法。

二、SpringBoot整合Redis加入Redis依赖及序列化依赖

    org.springframework.boot
    spring-boot-starter-data-redis



    com.alibaba
    fastjson
    1.2.76

三、增加Redis配置类,为key、value配置序列化方式
package com.test.redis.redis;

import com.alibaba.fastjson.support.spring.FastJsonRedisSerializer;
import org.springframework.boot.autoconfigure.condition.ConditionalOnMissingBean;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.data.redis.connection.RedisConnectionFactory;
import org.springframework.data.redis.core.RedisTemplate;
import org.springframework.data.redis.core.StringRedisTemplate;
import org.springframework.data.redis.serializer.StringRedisSerializer;


@Configuration
public class RedisConfig {

    @Bean
    @ConditionalOnMissingBean(name = "redisTemplate")
    public RedisTemplate redisTemplate(RedisConnectionFactory connectionFactory) {
        RedisTemplate redisTemplate = new RedisTemplate();
        // fastjson序列化
        FastJsonRedisSerializer fastJsonRedisSerializer = new FastJsonRedisSerializer(Object.class);
        // key的序列化采用StringRedisSerializer
        redisTemplate.setKeySerializer(new StringRedisSerializer());
        redisTemplate.setHashKeySerializer(new StringRedisSerializer());
        // value的序列化采用FastJsonRedisSerializer
        redisTemplate.setValueSerializer(fastJsonRedisSerializer);
        redisTemplate.setHashValueSerializer(fastJsonRedisSerializer);
        redisTemplate.setConnectionFactory(connectionFactory);
        return redisTemplate;
    }

    @Bean
    @ConditionalOnMissingBean(StringRedisTemplate.class)
    public StringRedisTemplate stringRedisTemplate(RedisConnectionFactory connectionFactory) {
        StringRedisTemplate stringRedisTemplate = new StringRedisTemplate();
        stringRedisTemplate.setConnectionFactory(connectionFactory);
        return stringRedisTemplate;
    }

}

四、配置Redis工具类,将RedisTemplate的API统一管理
public class RedisUtil {

    @Autowired
    private RedisTemplate redisTemplate;

}

五、RedisTemplate针对Redis五种数据类型的操作
